WILLIAM S. HALSEY, OF PI'IFSBURG, PENNSYLVANIA.

HOISTING AND CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 671,797, dated April 9, 1901. Application filed November 23, 1900. Serial No. 37.484. `No modelo T0 all whom it may concern/ Be it known that I, WILLIAMS. HALsnY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Hoisting and Conveying Apparatus, of which improvement the following is a specification.

The object of my invention is to provide a simple, compact, and effective mechanism by the employmentV of which a load may be raised and lowered and traversed horizontally between desired points of reception and delivery.

'lhe improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation of a hoisting and conveying apparatus, illustrating an application of my invention; Fig. 2, an end view, partly in section, of the same; Fig. 3, a side view, partly in section and on an enlarged scale, of a portion of the controlling-shaft and accessories by which the hoisting and the traversing gearings are operatively connected with and disconnected from the motor-shaft; Fig. 4, an end view in elevation of the same; and Fig. 5, a longitudinal central section, on an enlarged scale, through the motor.

In the practice of my invention I provide a wheeled traversing frame or trolley composed of two vertical side frame members 1 1,

connected by transverse bolts 2 and nuts 3 and having axles 4 journaled in bearings near their tops, on which axles are secured bearing-wheels 5 and spur driving gearwheels 6. The bearing-Wheels 5 are adapted to traverse an elevated track or runway, which in this instance is shown as the lower anges of an I-beam 7, which is supported at a desired height in any suitable and preferred manner. A hoisting mechanism is connected to and supported upon the lower portion of the trolley and a motor is mounted on the trolley between the bearing-wheels and the hoisting mechanism, rotative movelment being imparted by the motor either to the bearing-wheels or to the hoisting-drum, as may be desired, through intermediate gearing and controlling mechanism, as hereinafter described.

The actuating-motor, which may be either fluid-pressure or electric and which does not in and'of itself form part of my present invention, is mounted in a motor-case 8, secured to the frame members 1 of the trolley. The motor is herein shownas a fluid-pressure engine, which accords substantially with that set forth in Letters Patent of the United States No. 663,885, granted and issued to me under date of December 18, 1900. The cylinders 53 are tted with pistons 5+, which are coupled by connecting-rods 55 to a crank-pin 56 on a crank-arm 57, xed upon a main or driving shaft 9, which is journaled in bearings lOin the motor-case 8. The supply and exhaust of motive iiuid to and from the cylinders 53 is controlled bydistribution-valves 5S, which are reciprocated through eccentricrods 59 by a shifting or adjustable eccentric 60, which is fitted freely upon the drivingshaft 10 and is adapted to be moved transversely thereon, so as to either lead or follow the crank-arm, and consequently to cause rotation to be imparted to the driving-shaft in one or the other direction, as desired. The adjustment or reversal of position of the eccentric 60 is effected through a reversing-arm 3l, fixed upon a reversing-shaft 32, which is jonrnaled in a bearing in the motor-case 8. The eccentric 60 is provided with oppositely-extending arms 61 62, one of which, 6l, is pivoted to an arm 63, fixed upon the driving-shaft 9, and the other, 62, is pivoted to an arm 64, fixed upon a sleeve 65, which is fitted to move circumferentially on the shaft 9 and Vis provided with opposite helical grooves 66. A reversing-sleeve 30, fitted to move longitudinally, but not circumferentially, on the driving-shaft 9, is provided near one of its ends with pins 67, which engage the helical grooves 66, and at its opposite end with a circumferential groove 68, which is engaged by pins end of the reversing-arm 31. It will be seen that under the construction above described the rocking of the reversing-shaft 32 in its bearing will impart longitudinal movement in one or the other direction to the reversingsleeve and corresponding transverse movement to the eccentric, by which the reversal of the latter is eected. The end of the driving-shaft 9 which projects fromthe motor-case carries a trolley driving spur-pinion 11 and a hoist driving spur-pinion l2 of larger 69 on the free' IOO ' seen that when rotation in one or the other,

diameter. The pinion 11 engages with a spur-gear 13, Vwhich is fitted freely on a shaft 14, journaled in bearings in the frame members 1, and av clutch-coupling section 15 is formed upon or fixed to the outer face of its hub. Two spur-gears 16, fixed upon thel shaft 14 adjacent to the inner sides of the frame members, engage corresponding gears 17 on shafts 18, journaled in the frame members above and parallel with the shaft 14, and each of the gears 17 engages the drivinggears 6 of the two adjacent axles 4 of thev trolley-bearing wheels 5. It will thus be direction is imparted to the shaft 14 of the gear 13 corresponding longitudinal movement will be imparted to the trolley on the lower track-flanges of the I-beam 7.

The hoist driving spur-pinion 12 engages a larger pinion 19, 'xed on a shaft journaled below the pinion 12 in the adjacent frame member 1, and the pinion 19 in turn engages a spur-gear 20 of substantially greater diameter, which is fitted freely on a shaft 2l, journaled in a bearing 22, fixed to a bracket or hanger 23, which is secured to the lower portions of the frame members 1. A clutchcoupling section 24 is formed upon or fixed to the outer face of the spur-gear 20, the shaft 21 of which carries a Worm 25, meshing with a worm-wheel 26, fixed upon a shaft 27, which is journaled in bearings 28 in the bracket 23, transversely to the shaft 2l. A hoistingdrum 29 is xed upon the shaft 27. The reversing-shaft 32, through which, as before explained, the reversing mechanism of the motor is actuated, is provided with two oppositely-projecting arms or pendants 33, having eyes at their ends for lthe reception of cords or chains, by which they may be moved by an operator at a lower level to rock the reversing-shaftin either direction in its bearings, as may be desired. imparted to the shaft 21 of the gear 20, the drum-shaft 27 and hoisting-drum 29 will through the gearing above described be correspondingly rotated.

In order to enable either the driving-gearing of the trolley or that of the hoisting-drum to be actuated independently, but not coin- -cidently, by the motor, a controlling-shaft 34 is journaled in bearings 35 on one ofthe frame members 1, said shaft having oppositely-projecting arms 36 37, which when neither system of gearing is being actuated by the motor stand in a substantially vertical position. The arms 36 37Aof the controlling-shaft are fixed upon a hub or sleeve 45, which is tted freely on the controlling-shaft and is flexibly connected thereto, as hereinafter described, and they are forked attheir ends, and the jaws of their forks are provided with pins 38 39, respectively. The pins 38 of the upper arm 36 engage a circumferential groove in a clutch-coupling section 40, which is fitted to slide longitudinally on a keyor feather 41 on the shaft 14 of the gear 13 and is provided When rotation is with jaws on itsinner face adapted to engage the corresponding jaws of the clutch-coupling section 15, which is fixed to the gear 13. The pins 39 of the lower arm 37 engage a circumferential groove in a clutch-coupling section 42,:which is tted to slide longitudinally on a key or feather 43 on the shaft 21 of the gear 20 and is provided with jaws on its inner face adapted to engage the corresponding jaws of the coupling-section 24, which is fixed to the gear 19. Arms or pendants 44 are fixed to the controlling-shaft 34, said arms projecting oppositely therefrom at right angles to the `arms 36 and 37 and being provided with eyes at their outer ends for the reception of cords or chains for operation from a lower level. A sucient downward movement of the lefthand arm 44 of the controlling-shaft will move the lower arm 37 thereof to the right and effect the engagement of the coupling-sections 42 and 24, thereby imparting rotation through the gear 2O to the shaft 21, and thence through the'worm 25 and wor1n-wheel 26 to the hoisting-drum shaft 27 and the hoisting-drum 29, which is fixed thereon. A corresponding movement of the right-hand arm 44 will move the upper arm 36 of the controlling-shaft to the right and effect the engagement of the coupling-sections 40 and 15, thereby imparting -rotation through the gear 13 to the-shaft 14, and thence through the gearing 'before described to the bearing-wheels 5 of the trolley. The connection of the shaft 21 with the hoisting-d rum shaft 27 being through a worm and worm-wheel, the dropping of a load attached to the hoisting-drum will not result when the coupling-sections 42 and`24 are disengaged.

In order to enable the engagement of the members of either of the two pairs of coupling-sections to be eected while the motorshaft is in rotation, a flexible connection of the arms 36 and 37 with the controlling-shaft 34 is, as before indicated,provided. To this end one of said arms, in this instance the arm 36, is connected to one end ofa helical spring 46, which encircles the controlling-shaft 34 and is connected at its opposite end to an arm 47, fixed upon said shaft. A segmental recess 48, which is concentric with the shaft, is formed in the arm 47, one of the ends of said recess abutting when the arms 36 37 are moved into position to effect the engagement ofthe members of either pair of coupling-sections on a stop-pin 49, which fits freely in the recess and is secured in a standard 50, fixed to one of the bearings 35 of the controlling-shaft. A latch-'bolt 51, having a tapering or conical end and which is pressed outwardly by a spring 52, is fitted ICO freely in a recess in the outer end of the arm 47 and is adapted to engage any one of three locking-recesses 53, which are formed in the adjacent side of the standard. The central one of the locking-recesses holds the arms 36 and 37 in their neutral position-that is to say,.that in which neither of the two Ycouplings is engaged-and the two outer recesses,

respectively, hold said arms in position for ism, as the case may be. As the spring 52 constantly acts to force the latch-bolt 51 into and hold it in the recess of the standard opposite to which it may be brought by the movement of the controlling-shaft by the operator and as a limited degree of independent traverse of the arms 36 and 36 and the arm 47, respectively, is permitted by the iiexible connection of said arms, the engagement of the latch-bolt with a locking-recess may be readily eifected, as desired, while the motorshaft is in rotation.
